the model of the processor 17 is STM32F107VCT6, and the processor has a storage function;
the display screen 29 is a signal that the touch display screen 29 can accept external input.
When the device is used, the power supply is connected with the mains supply, and the power supply converts the mains supply into working voltages required by various components in the device. The touch display screen above the control panel starts to display pictures, an operator firstly transmits three-dimensional model data of the parts to be classified to the classifying device for part recognition through the data transmission port, and a processor in the device has a storage function and can store three-dimensional models of more than 500 parts. In this embodiment, 3 kinds of parts are identified and classified.
After the operation is finished, an operator selects a working mode by clicking the touch display screen through a finger, the device is activated to be in a standby state, then the operator pours the parts to be classified into the storage hopper, when the parts are stored in the storage hopper, the parts to be classified are directly related to the pressure of the upper parts due to the static friction force and the pressure of the objects, the static friction force is increased, and therefore the parts to be classified cannot fall onto the first conveyor belt from the vibrating plate.
The operator then changes the device into a working mode by operating the touch display screen, and selects the specific 3 parts which need to be subjected to part identification and classification for the specific implementation, the device starts to work, vibrators in the vibrating plate start to reciprocate rapidly, vibration is transmitted to the parts to be classified below the storage hopper, the parts to be classified below are subjected to vibration, the pressure of the parts above is temporarily lost, and the parts gradually fall down along the vibrating plate along with continuous vibration. Along with the continuation of vibrator vibration, wait to classify the part and shake out to first conveyer belt by orderly, avoided the part to pile up together and influence the image acquisition of camera.
The first motor outputs power to drive the first transmission shaft to move, the first driving wheel matched with the first transmission shaft starts to rotate clockwise, the first conveyor belt starts to move clockwise at the speed of 0.2m/s under the joint cooperation of the first driving wheel and the first driven wheel, the camera on the fixed column starts to work, when the device is in a working mode, the light supplementing lamp on one side of the camera lens is normally on, the light supplementing lamp is an led cold light source light supplementing lamp, the long-time working can be at a normal working temperature, and the working of the camera and other parts cannot be influenced.
The stable light source that the light filling lamp provided can improve the image quality that the camera gathered greatly, improves the subsequent efficiency of treating the comparison and distinguishing between classifying part and the part that needs classifying of treater.
The camera at the forefront end of the first conveyor belt can transmit back the images of the parts to be classified to the processor, the processor can compare the transmitted images with the first of 3 three-dimensional models of the parts selected by operators, if the images transmitted back by the camera basically accord with the first of the 3 three-dimensional models of the parts in the processor, the camera can send out working instructions to the single-acting cylinder, because the running speed of the first conveyor belt is constant at 0.2m/s, the single-acting cylinder is just in front of the silica gel pad after receiving the instructions of the processor to start stretching for 1s, the single-acting cylinder pushes the piston rod to start moving, the piston rod pushes the silica gel pad in front to move, the parts to be classified on the first conveyor belt is pushed down, the parts to be tested are pushed down the first conveyor belt by the extended silica gel pad and fall into the part collecting box, and the classification of the first of the 3 three-dimensional models selected by operators is completed.
If the returned image cannot be successfully compared and matched with the first part of the three-dimensional model of the 3 parts to be classified, the single-acting cylinder is silent. The parts on the waiting conveyor belt pass through the front-end camera and sequentially pass through the two subsequent cameras above the first conveyor belt, and when the parts pass through, the 2 nd and 3 rd three-dimensional model data in the 3 parts to be classified are sequentially compared and resolved, and the principle of executing related operations after each comparison and resolution is the same as that of the parts passing through the first group of cameras.
If the parts to be classified pass through the first conveyor belt completely, the first conveyor belt is not pushed down by the piston rod on the electric push rod, and falls into the corresponding part collecting box. The parts to be classified may be non-target parts, or slip occurs on the first conveyor belt and the subsequent parts to be classified are stacked, and cannot be identified, or abnormal parts posture cannot be identified, etc.
The parts to be classified continue to move forward, completely walk through the first conveyor belt, fall on the guide plate under the action of gravity at the end of the first conveyor belt, collide with the guide plate, disintegrate the stacked parts to be classified, obtain a new posture of the parts with abnormal postures, and fall on the second conveyor belt from the lower part of the guide plate.

In contrast to the first classification on the first conveyor belt, the first classification on the second conveyor belt is the classification of the three-dimensional model of the last of the 3 parts to be classified. To match the parts pushed down on the first conveyor belt into the parts collection box, the specific identification and classification method is the same as the previous description.
After the second identification and classification is completed, 3 parts selected by basically all operators are identified and classified, and the 3 parts fall into corresponding part collecting boxes. Finally, most of the parts passing through the end of the second conveyor belt are non-target parts, and the non-target parts are conveyed to the collecting plate by the second conveyor belt along with the movement of the second conveyor belt, the collecting plate is fixed on the middle opening of the left side of the box body, and the non-target parts are conveyed out by the second conveyor belt and are collected by the collecting plate to fall into the non-target part collecting box.
